We got the report to find the Sempron with the problem from Germany.
Thank you.
I hear that abnormality was found in the detected voltage and the state of the bridge in this CPU.
Some certainly doubtful points were found from this photograph.

The OPN label is being written AMD Sempron SDA2800DUT3D. This shows CPU for desktop for which the thoroughbred core is used, and ratings are the following.

However, common feature to Mobile CPU such as Athlon XP-M and Geode NX was seen in this CPU. Enlarge of image

Please attention to the character of AMD and Sempron of the OPN label.
In The truth Sempron, the character of AMD and Sempron is almost the same thickness, and
a bold font is used.
However, because the character written Sempron is thin in this Sempron, it looks poor.

Remarked Sempron 2800+

The true AMD Sempron ( For reference )

L bridges of fake Sempron2800+

It turns out as watching the L bridges whether it is fake Sempron.

It is L6 bridge. There is no laser pit in this L6 bridge in CPU for desktop like Athlon XP and Sempron, etc. at all.

It is only mobile CPU that in the L6 bridge with the laser pit. The ratings multiplier can be originally presumed to be 10.5X from this pit.

The true Sempron doesn't have the pit in L6.

The L8 bridge is not used in CPU for desktop either. They are all closed without the exception. However, there is a laser pit in this photograph.
Moreover, it is unnatural that the pit is in the center of the L11 bridge.

There is a laser pit in both L8 and L11 the feature of mobile CPU. The rated voltage can be estimated to be 1.25V from the state of this L8.

The true Sempron doesn't have the pit in L8.

What is this?

I got this report from Mr. J.Mittelstaedt of Germany.
When depending on it.
The voltage of this Sempron 2800 was 1.725V and automatic detected according to purchase.
The rated voltage of Sempron 2800 is 1.60V.
Therefore, we think that it is a remark. Maybe, it might be Geode NX1750.

This CPU is being investigated by AMD now. (March 01)
......Afterwards, there was an answer from AMD. (March 02)AMD has now confirmed that the Processor is remarked.

Remarked Sempron 2800 in Finland [ March 24, 2006 ]

It is a continued report of doubtful Sempron in a European market.
The following photographs have been sent by Finland. When this is seen, it is understood that
CPU is not Sempron.

There is an abnormal laser pit in these bridges. Judging from the bridges, the original CPU is Geode NX 1750.

The report from Mr. S.Ahvenlammi of Finland is the following.

Here is a picture of one Socket A Sempron 2800+. It is remarked AMD Geode
processor as you can see from OPN sticker.
This processor was bought from one Finnish computer component store a couple
of weeks ago. I have sent processor back to them and they will investicate
what is going on. Most likely it has been shipped to Finland from Germany.

You will be able to read the character of Geode according to the expectation.

Remarked Sempron 2800 in Russia [ March 25, 2006 ]

There was a report from Moscow.
The following CPU will be sure to be a fake.

Judging from the bridges, the original CPU is Geode NX 1750.

The report from Mr.VeT of Moscow is the following.

I purchased today this CPU in Moscow.
Motherboard (Abit NF7-S rev. 2.0) detected it as Sempron 2800+
(166MHz x 12), but V_core was 1.775 V. After several minutes of
work my computer was turned off itself. With the reduced operating
frequency the work of computer became stable.

Remarked Sempron 2800 in Czech Republic [ April 10, 2006 ]

We got the report from Mr.Ferroun of Czech Republic. It is the following.

I'm from Czech Republic and I found on AMD Forums the thread about remarked Semprons 2800+ just one day after I bought it. After some checks I realized, that my new proc is almost sure fake also. I'm writing you only for to let you know, that also in CZ there are some fakes on market :-( I'd appreciate, if you could public this on your web.

More information will be obtained in the photograph than my strange English. Please refer to the following for an original photograph and a related content.

and here's link to my web with some screenshots and photo of my fake Sempron

Remarked Sempron 2800 in France [ April 14, 2006 ]

We got the mail from Mr.Marc of France. Needless to say, this Sempron is a fake, too.

I'm french, I bought it in Lille (north of France).
Because my sempron2800 looks alike to the example of Russian, I think
that it is a fake.
The default core voltage is 1.775V (not 1.6V as it should be).

Remarked Sempron 2800 in Germany [ April 26, 2006 ]

We got the mail from M.Heinisch of Germany.

Hi,last month I found your page about these fake Sempron 2800+.
After I bought a Sempron 2800+ in January from a german Internet store.
I noticed immediately that the Voltage was too high, but the Support told me that the mainboard may cause the problem and I shouldn't worry about that...
But because of the Information on your website I discovered that I own one of these fake Semprons, and hopefully I get a real one from the Store now.

Thank you for your report
